Why are covalent-network substances poor electrical conductors?
There is generally a lack of free electrons to conduct electricty. For example diamond (an allotrope of carbon) and silicon dioxide, which are very poor conductors. . Some network covalent t are semiconductors- like silicon- which mean that they can conduct but poorly.
Thermal conductors are substances that do what?
They are good and conducting and transferring heat.
Which metal acts as an insulator?
Metals are conductors, not insulators. Both electrical and thermal conductors.
Out of ionic pure covalent metallic and polar covalent which is most likely to conduct electricity?
All types of covalent compounds are not very good conductors of electricity. However, ionic compounds in their molten state and metallic substances are very good conductors of electricity.
Which two substances could be good thermal conductors?
aluminum and copper.
What are substances that allow electrical charges to pass through them?
Conductors
What are some good conductors and bad ones?
Good Electrical conductors: All metals, ionic substances (in solution or molten form) Bad Electrical conductors: Water Good Heat conductors: All Metals Bad Heat Conductors: Water
What Types of building materials are conductors and insulators?
electrical
How were electrical conductors discovered?
in 1729, Stephen Gray, an English physicist, found that some substances could carry electricity from one location to another. These substances were called conductors.
What is an electrical insulator an conductor?
The substances that do not conduct electricity are called electrical insulators while those which conduct electricity are called conductors.
In what types of products are conductors used?
Conductors are used in every electrical product and device that is manufactured. Without the conductors there would be no path for the electricity to travel.
What does an electrical current flow in?
Electrical conductors.
What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
Which of these has the greates effect on the electrical conductivity of solutions?
Influence on the electrical conductivity of solutions:- types of substances dissolved- concentration of solutes- temperature
What are some examples where electrical conductors are used for?
Electrical conductors are used in wiring. They allow electricity to flow through the wire and into the item needing the electrical power. Wires are usually made of copper or aluminum because these metals are good electrical conductors.
How do electrolytes conducts electricity?
by charge transport and transfer ........they are substances whose aqueous solution are conductors of electricity..electrolytes are good electrical conductors while non electrolytes do not conduct electricity ..........
Does all the substances conducteed electritcy show the same amount of conductivity?
no all the conductors do not have the same electrical conductivity as copper is a good conductor and silver is the best but it is costly.
